Send your binaural-beat programme to YouTube Live as stereo, confirm that the intended left and right signals reach OBS, and keep the levels conservative. A limiter can control peaks, but it cannot correct crossed, missing or downmixed channels; listen to a representative recording and check the YouTube preview before broadcasting.
The checks below separate channel routing from clipping, then cover source gain, the limiter, encoder settings and live monitoring. They concern the audio delivered by your setup, not any claimed effect of binaural beats.
Preserve the intended left and right channels
A stereo source has distinct left and right channels. If your programme is designed with different signals on each side, preserving those assignments through OBS matters: a quiet meter on one side, a mono downmix, or a channel swap can change what reaches the viewer even if the audio is not clipping.
Start with the file or player you intend to use. Play a section where you expect both channels to be active, and check the player’s output or channel configuration. If you can listen locally, use stereo headphones as a simple way to notice a channel that is missing or unexpectedly placed. This check does not establish anything about the programme’s effects; it is only a practical check of what is sent to each ear.
Keep the source in stereo from playback through OBS and the stream. Avoid enabling a mono downmix when the intended programme depends on separate left and right signals. A mono mix may sound audible and may show meter activity, while still removing the separation you meant to preserve. Likewise, swapping channels may not produce clipping, but it changes the assignment.
Think of routing and level as separate questions. Routing asks whether the correct signal reaches the correct side. Clipping asks whether the signal becomes too high somewhere in the path. Lowering a fader may reduce a clipped signal downstream, but it will not restore a channel that was lost earlier. A limiter has the same boundary: it can restrain peaks, not repair channel assignment.
If you have previously used a mono source or a different OBS scene, check the settings rather than assuming the current scene inherits the right arrangement. Make one change at a time, then listen again. For a broader view of the options for running an always-on channel, our guide to streaming software for beginners gives context for the role OBS can play in a setup.
Check stereo routing in OBS
In OBS, inspect the audio settings and the source itself before adjusting levels. OBS uses stereo by default, and its audio mixer represents left and right activity for a stereo source. While the actual programme is playing, watch both sides of the relevant meter. The official OBS Audio Mixer Guide explains the mixer, monitoring and recording checks.
A meter showing activity on both sides is useful, but it is not a complete routing test. It does not prove that the sides contain the intended content or that the final encoded stream preserves it. Listen to the monitored signal, and later listen to a test recording. If your source is a browser, media player or capture device, check that OBS has selected the intended device and that the source is not duplicated through another input.
Look for accidental duplication in the mixer. Capturing the same player both as desktop audio and as a separate application source can make the signal louder or produce an echo, depending on how the sources are monitored and mixed. Muting one route temporarily can help identify which input is carrying the programme. Restore the route you intend to use before testing the final mix.
Also check for channel controls on the source, device or operating system. A device configured as mono, a channel balance set hard to one side, or an unwanted downmix can produce symptoms that a master fader adjustment will not solve. If one side is silent in OBS, trace the path from the source output to the selected OBS input before adding filters.
Do not confuse meter movement with correct sound. A routing error can leave both meters active, for example if the same mono signal is sent to both sides. Listen to the OBS monitor output if you have configured one, and compare it with playback from the source. Headphones connected to a monitor output can help you hear a missing side or duplicate capture; they are an optional checking aid, not a clipping remedy.
Set conservative source levels
Set gain in order, starting upstream. Check the player’s own volume, the operating-system mixer or device output, and then the OBS source fader. If you lower only the final fader after an earlier stage has already distorted, that earlier distortion remains in the signal. Conversely, turning every control up and relying on a limiter can make the limiter work constantly and obscure where the problem began.
Play the loudest or densest part of the actual programme while watching OBS’s peak meter. Avoid setting levels using silence or a quiet introduction. OBS notes that audio exceeding 0 dBFS in a recording or stream can result in clipping distortion. Its mixer documentation describes -9 dBFS as a “Permitted Maximum Level” reference, with margin for discrepancies in meter readings and alignment between equipment. Treat that as a conservative OBS reference, not as a YouTube loudness target.
The practical aim is to leave headroom for peaks and for changes in the actual playback chain. If the meter reaches its top or shows clipping, reduce the source or earlier output level and listen again. Do not compensate by raising another stage without checking the resulting meter. A fader position alone does not tell you the signal’s peak level; the source material and upstream gain also matter.
Make adjustments with the final source and scene active. A test using a different track, player or device may not reveal a peak in the programme you will broadcast. If a file is being looped, sample its loudest transitions and any changes in programme material. If clips are joined, a transition or overlapping sound can create a higher combined peak than either passage alone.
Keep overall loudness distinct from peak control. A conservative peak level does not necessarily mean the programme will sound as loud as another channel, and raising loudness is not required to fix clipping. First ensure the audio is clean and the channels are correct. Adjust perceived level only after listening at a comfortable, repeatable volume, and avoid driving the chain into distortion to make it seem louder.
For more on keeping a long-running channel stable beyond the audio path, see our guide to YouTube streams that drop after a few hours. That is a separate operational problem: a clean audio mix does not prevent a connection or stream session from dropping.
Place a limiter last in the filter chain
Once routing and gain staging are sensible, a limiter can serve as a final peak ceiling. In OBS, add the Limiter filter to the relevant source and place it after the other audio filters. The OBS Limiter Filter documentation recommends placing the limiter last in the filter chain and describes its role in preventing peaks above 0 dB that may cause clipping and distortion.
OBS documents a default threshold of -6 dB and release of 60 ms. Those are software defaults, not a universal mastering prescription or a guarantee that the delivered stream cannot clip. Start by understanding what the controls do, then listen to the result and observe whether the limiter is acting frequently. If it is constantly reducing the signal, revisit the source level and earlier gain stages rather than treating heavier limiting as the first fix.
The order matters because a later filter can raise or otherwise alter the signal after the limiter has acted. Putting a limiter before such a filter means it is no longer the final control on peaks in that chain. After changing filter order or adding processing, test again. A limiter cannot undo distortion already present in the source, recover a missing channel, or repair a mono routing decision.
Use the limiter as a safeguard rather than as a substitute for monitoring. Its output may sound more controlled while still having a routing problem, poor balance or an unpleasant change in dynamics. Compare playback with the filter enabled and bypassed at a similar listening level. Listen for abrupt changes or pumping, and check meter behaviour during a loud passage.
If you prepare source audio in another editor, remember that processing the file and processing the live OBS path are different stages. Audacity’s limiter, for example, can shape peaks in a prepared file, but the live source, OBS filters and encoded stream still need to be checked together. The final broadcast is the result of the whole signal path, not just the exported file.
Use YouTube’s recommended stereo encoder settings
Keep platform encoder recommendations separate from the limiter workflow. For RTMP or RTMPS live ingestion, YouTube’s recommended live encoder settings list AAC or MP3 audio, a 44.1 kHz sample rate for stereo, and 128 kbps audio bitrate for stereo. These are YouTube’s audio encoder recommendations; they do not set your source gain, correct routing or make a clipped source clean.
In OBS, check the audio encoder settings for the streaming output you actually use. Avoid assuming that a setting in a local recording profile automatically matches the live stream profile. If you record and stream with different configurations, make a test recording and inspect the live preview separately. A local file can be clean while a different output path is configured incorrectly.
Do not mix the audio guidance up with the video bitrate table on YouTube’s page. Video resolution and frame-rate choices affect the visual part of the stream and the required upload capacity. Choose video settings appropriate to the visual you are showing and the connection available, then test the combined stream. YouTube’s live streaming tips advise allowing room against available upload bandwidth; do not assume an audio setting alone determines whether the stream remains healthy.
If your stream is primarily a still image or slow visual loop, avoid changing video settings while troubleshooting audio unless you have a reason to do so. Change one part at a time and note what you changed. That keeps an audio-routing test from becoming a broad encoder experiment where the cause of a problem is hard to identify.
Test a representative preview and recording
Before going live, test the full path with audio that resembles the actual broadcast. Include the loudest programme section, transitions and any playback conditions you expect to use. YouTube recommends testing with audio and video movement similar to the event. In YouTube Studio’s Live Control Room, check the preview and stream health before starting the public broadcast.
At the same time, record a representative session in OBS. Then listen to the recording, not just to the source player. OBS advises recording as you normally would and listening back before going live. Check that left and right are present and correctly assigned, the sound is free of obvious distortion, and transitions do not produce sudden peaks. A recording provides a chance to review the actual OBS output without having to rely on memory while adjusting controls.
Compare three points if you can: the source player, OBS monitoring and the recorded or encoded result. If the source sounds clean but the recording distorts, the issue is likely further downstream in the OBS or output path. If OBS meters show a peak but the recording sounds clean, do not ignore the reading; inspect the filter chain and output. If the sides sound wrong already at the source, fix that before adjusting OBS processing.
The YouTube preview adds another check: it can reveal issues after the signal has gone through the live encoder path. Listen for missing or swapped channels, distortion, level changes or unexpected silence. A preview is not a substitute for checking your local recording, because the two checks answer different questions. The local recording helps assess OBS’s path; the preview helps assess what YouTube is receiving.
A short test only helps if it represents the real programme. If the stream runs from a long file or repeating playlist, test a section with the busiest audio and a point where one item changes to another. If you rotate tracks or playlists, include a transition. A quiet opening loop is a poor test of peak handling if the later material is louder.
If you need to leave your computer off during an always-on broadcast, the practical constraint is different from an OBS session you are personally monitoring: you still need to check the prepared file and live result before relying on unattended playback. StreamNeo removes the need to keep your own computer running for an uploaded-file YouTube stream, but it does not replace your responsibility to verify the audio and channel before broadcasting. For a different route using your own hardware, see how to run a 24/7 music stream from a Synology NAS.
Monitor meters during the live broadcast
During the broadcast, keep OBS’s mixer visible when possible and watch the peak indicators while the programme plays. OBS’s peak indicator holds the recent loudest level for 20 seconds, which can help you spot a peak that occurred between glances. A held peak is a prompt to inspect the signal; it does not by itself tell you whether the recorded output audibly distorted.
Also watch YouTube’s stream health and messages in Live Control Room. YouTube recommends monitoring the quality of the live stream. These checks cover different layers: OBS meters help you see levels in the local mix, while stream health can show problems with the outgoing stream or ingestion. Neither replaces listening to the audio reaching viewers when you can do so.
If you hear distortion, identify where it begins rather than changing several controls at once. Check whether the OBS source meter is peaking, whether the source itself is already distorted, and whether the issue occurs in the local monitor, the recording, the preview or only after going live. Reduce gain at the earliest stage that is actually too high, then repeat a test. If one side disappears, return to the routing checks rather than lowering the master level.
For an unattended or overnight channel, establish a routine before leaving it to run: confirm the correct scene and source, ensure the limiter remains last after any filter changes, check the live preview, and look at the meters during the opening section. If the audio programme changes, test that material rather than assuming a previous test covers it. A setup can be correct for one file and wrong for another.
Keep notes of the working source, device and OBS settings. That is more useful than relying on a remembered fader position after changing a player, operating-system device or scene. If a problem returns, compare the path with the last known clean recording and make one deliberate change at a time.

FAQ
Does a limiter fix incorrect left and right routing?
No. A limiter controls peaks; it cannot restore a missing channel, swap channels back or undo a mono downmix. Check the source and OBS routing, then use a limiter only as peak control.
What audio settings does YouTube recommend for stereo live audio?
YouTube’s RTMP/RTMPS encoder guidance lists AAC or MP3, 44.1 kHz and 128 kbps for stereo audio. Check YouTube’s current live encoder page before a broadcast in case its guidance changes.
If OBS meters stay below 0 dBFS, is clipping impossible?
No setting or meter check guarantees that the final stream cannot clip. Check the source, the full OBS chain, a local recording and the YouTube preview; each can reveal a different part of the signal path.
Do I need headphones to test the stream?
Headphones are optional, but they can help you hear left/right placement and compare the source with OBS monitoring or a recording. They do not prevent clipping, so still watch the meters and listen to the recorded and encoded result.
